From karchin@physics.wayne.edu Tue Aug 24 14:42:02 2004 Date: Fri, 11 Jun 2004 10:26:49 -0400 (EDT) From: Paul Karchin To: Arthur Maciel , Gene Fisk , Mani Tripathi , Mitch Wayne Cc: Paul Karchin Subject: Muon Abstract for DPF Dear All, Since I am planning to attend DPF, I would like to submit an abstract for the muon system. Below is a proposed abstract. It covers only hardware, not simulation. If any of you want to submit a separate abstract on aspects of the hardware I am happy to take that out from mine. Who would be interested to submit an abstract on the simulation? There will be DOE people at DPF, and we need to press our case. All suggestions are welcome. Regards, Paul ------------------- A Scintillator Based Muon Detector for the Linear Collider Paul Karchin representing the American Linear Collider Muon Collaboration The muon system is the largest part of a detector for a future high energy electron positron linear collider. This poses the challenging task of designing a cost- effective, large area, finely- segmented muon detector that will provide stable operation for many years. A large dynamic range in energy may be required to measure shower leakage from the hadronic calorimeter. A fast time resolution may be required to reduce backgrounds and to detect long-lived exotic particles. A promising technology option is based on scintillator strips with embedded wavelength shifting (WLS) optical fibers that are readout by multi-anode photo-multiplier tubes. Results will be presented on measurements of light yields from the scintillator, WLS fibers spliced to clear fibers, and photo-electron yields from Hamamatsu multi-channel phototubes. The design and performance of prototype phototube readout electronics will also be presented.
